This week we look at a tool for Responder to use for exploring slam after partner opens the bidding with a 2-level or 3-level preempt. When we respond to a preempt, the auction can reach a very high level very quickly. When we are interested in exploring slam we want to be able to ask for Keycards and keep the auction as low as possible. Let's look at how we can use this tool to do that.
